Abstract: An off-shore berth for a ship, particularly a tanker, is described in which roll, pitch and yaw are neutralized. The ship is tautly attached to barges, one on either side, and a beam under the ship's keel is coupled to the barges. The beam is tethered to a permanent anchor in the sea floor.

Abstract: A barrier device comprising a plurality of gated structures extending between opposite shores of a tidal estuary provides a means of preventing intrusion of heavier, colder sea water with each incoming tide and to then be the means for ejecting large volumes of collected sea water together with mud, sand and sewage pollutants. The eventual effect will be to create a body of fresh water of previously unattainable purity. This purity is renewable with the discharge of any excess water available. During periods of heavy withdrawal from the upstream pool all gates can be locked closed. After danger of flooding has ended the upstream pool can then store a very large volume of fresh water. Flood water is ejected as fast as it flows into the pool. Tidal power can be used to force flood water into the sea.

Abstract: A heavy duty flexible marine pipeline has the capability of being assembled on the surface of the sea. In order to do this a certain amount of slack is required in the pipeline. Both deep and shallow water systems are described. The deep water system has an operational minimum depth about midway between the sea floor and the surface. Tension force in the pipe sections is automatically compensated and is relayed to adjacent pairs of vertically taut anchor cables. The pipeline is buoyant and the flexible pipe wall has a very high bursting strength and the pipeline is therefore particularly adapted to deep water applications.
